I am – Hercules!! Not only has Joss Whedon directed tonight’s installment of “The Office,” J.J. Abrams has directed next week’s. (“Groundhog Day” mastermind Harold Ramis directed the series’ Christmas episode.) Here’s how NBC describes tonight’s installment:

"Business School" MICHAEL GOES TO BUSINESS SCHOOL WITH RYAN-- Ryan (B.J. Novak) invites Michael (Golden Globe winner Steve Carell) to be a guest speaker at his business school. Meanwhile, Dwight battles a bat that gets loose in the office while Pam (Jenna Fischer) invites co-workers to her first art show. Rainn Wilson, John Krasinski, Melora Hardin, Leslie David Baker, Brian Baumgartner, Kate Flannery, Angela Kinsey, Oscar Nunez, Phyllis Smith, Paul Lieberstein and Mindy Kaling also star.

If you’ve never heard of this Whedon guy, he wrote “Toy Story” and “Speed” (and a spectacular screenplay for “Alien Resurrection” that was never used) before he wrote and directed TV shows like “Buffy the Vampire Slayer,” “Angel” and “Firefly” and the movie “Serenity.” (By the way, I just purchased the latest issue of Whedon’s “Astonishing X-Men” this afternoon. The Angry Colossus cover is supercool, man.) If you don’t know who J.J. Abrams is, he wrote the insanely underrated “Regarding Henry” before he created “Felicity,” “Alias” and “Lost.” He also wrote and directed the last “Mission: Impossible” movie and is said to be hard at work on a new Kirk/Spock “Star Trek” movie and an adaptation of Stephen King’s “The Dark Tower.” My pal Kristin Veitch over at E! just called Whedon and Abrams “the two best TV directors alive.” Who are you to argue? 8:30 p.m. Thursday. NBC.
